PTCB Certified Pharmacy Technicians (CPhTs) are required to recertify every 2 years to maintain an active certification. PTCB's recertification requirements correspond with the biennial renewal schedule for professional pharmacist licensure as governed by State Boards of Pharmacy. Some employers and/or State Boards of Pharmacy require CPhTs to maintain their PTCB Certification. The purpose of recertification is to ensure that pharmacy technicians stay up-to-date in pharmacy practice through the completion of Continuing Education (CE).
